A prerequisite to the effective design of user interfaces is an understanding of the tasks for which that interface will actually be used. Surprisingly little task analysis has appeared for one of the most discussed and fastest-growing computer applications, browsing the World-Wide Web (WWW). Based on naturally-collected verbal protocoldata, we present a taxonomy of tasks undertaken on the WWW. The data reveal that several previous claims about browsing behavior are questionable, and suggests that that widgetcentered approaches to interface design and evaluation may be incomplete with respect to good user interfaces for the Web. Keywords World-Wide Web, task analysis, video protocols
